The relative position of the block 15 within the shifter connection l0 is determined by the position of thelstud 14 within the openin 19 of the shiftellji'ni 9, and the same is loc led in any of its positions by the screws 24 and 25-Which impinge against the opposite ends of the said block. .lt is'obvious that the closer the stud 14 is moved toward the center -of the shaft 8, the greater will be the arc through whichthe rock shaft i3 will travel, and vice versa, thereby provid- Y' ing means for varying the length of stroke of the fecd'mcchanism. It will be observed the mechanisms necessary to' accomplish this adjustment are upon the outside of the machine, are readily accessible, and easily controlled.

The dies are Vdesignated bythe numeral 27 and have alateral movement within the body .1 through the reciprocating action of travel so that the grooves in the meeting faces thereof pass from the line of the Wire feed of the heading operation, designated by the numeral 30. l`he dies .are-held against the plate 28 and returned to`the line 29 by mechansir'i comprising the plate 31 connected to the ends of the slidably mounted rods 32,

having a headbracket 33 thereon, against which the end of a s ring 34. is secured at lits opposite end to the body 1 by a cap 35.- A4 screw 36 threaded throughv the hea bracket 3 3 and abutting against the bed l, limits the inward movement' of the parts Just described.

Pivotally secured on the stud 374 is the trip latch 38 having trip arms '39 and v40 thereon, through the latter of which is an adjusting 'screw 41 that lies within the ath of movement of the head bracket 33. his latch is subject to the pressure of a sprin4 42 that bears against the end of a pin 4 3 conl tacting with the arm 39 and'actuates the said ll)atch to move the trip jarm 39 away from the Cbnnected with `the body 1 is 'a roll frame 44, within which *are rotatably mounted the shafts 45 and46, each of which isl provided with a feed roll 47 and intermeshing gears 48 and. 49. In one face of the gear 49 is a ring 50 and concentric therewith is a clutch plate 51 secured by screws 52, and having a plurality of notches 53 :in the edge thereof, 'said notches having roll faces' 54 andan end face 55. -Within leach of said notches is a roll 56 that vis moved in one direction between the face 54 and the inner face of the ring 50 by a pin 57 having a head 58 there- 0n with an angular face w ichI contactswith the roll 56.
